APPARATUS FOR REMOVlNG SlTAMPED METAL ARTICLES FROM DKIES.

VS1:IEIGIIERJTIQN forming part of Letters Patent No. 532,434, datedJanuary 8, 1895. Application filed November 16, 1393.V Serial No.491,121. (N model.)

1o drawings.

Myinvention relates to an apparatiisfor removingstamped metalarticlesfrom male dies. It is well known that in stamping metal r cylinders andother like articles great difticulty is often encountered in removingthe articles from the male die, owing to the tenacity with which theshaped metal adheres to the die, this being especially true where 2o anattempt is made to stamp up a cylinder of any considerable length.

The object of my invention is to provide means whereby, when the maledie, with the stamped article clinging to it, is raised out of thefemale die, heat may be applied to the entire outer surface of theshaped metal, so as to expand and loosen the article on the die.

With this object in view, my invention con sists in the novelconstruction and arrange- 3o ment of parts hereinafter described andclaimed.

Figure l of the drawingsis a vertical sectional view showing a stampedarticle on a male die or plunger, and also my apparatus 3 5 for applyingheat to said article to expand it so that it can be readily removed fromthe die. Fig. 2 is a top plan view of my apparatus for applying heat tothe stamped article. Fig. 3 is a vertical elevation of the same.

4o Referring to the drawings, D represents a hollow cylinder made of anysuitable material, and formed in sections, hinged together, as at 3. Theupper end of this cylinder is partly covered, the diameter of thecentral openingj being but slightly greater than the diameter of themale die or plunger. In this cylinder are a number of perforations 5, inwhich are inserted inlet-pipes 6, which communicate, throughbranch-pipes 7, with a 5o main pipe 8, the latter being connected to asuitable gas-supply D. The main pipe and branch pipes are made offlexible material, in order to facilitate the placing in position andremoval of the cylinder D, the latter be- '55 ing provided with handlesF. Openings 9 formedin convenient places in the cylinder serve to admitdrafts of air.

E represents a male die or plunger.

G represents a stamped article on the die.

In operation the cylinder D is placed around 6o the suspended die andthe stamped article thereon, when the upper end of the cylinder willrest on the upper edge of the article, as seen at 4. Gas being thenadmitted to the cylinder through the various pipes and lighted, the heatdeveloped, acting directly on the stamped article, will cause expansionof the latter, when the apparatus, which, as beforeV stated, issuspended from the upper edge oi'- the stamped article, will by gravitygradually 7o force thek article oit from the die. ,By this means alldanger of cracking or breaking the stamped article in the act ofremoving it is obviated.

Having thus described my invention, what 7 5 I claim as new, and desireto secure by Letters Patent, is-

1. An apparatus vfor removing stamped metal articles from male dies,consisting of a perforated cylinder adapted to encompass the 8o stampedarticle on the die and to be suspended from its'top edge, a gas-supply,a main pipe connected therewith, branch pipes con nected with Ythemain-pipe, and inlet-pipes 'leading from the branch pipes into thecylin- 8 5 der through the perforations in the latter, whereby when thegas is ignited and the article Vexpanded by the applied heatthe downwardpressure exerted by the weight of the apparatus will cause the removalof the arti- 9o cle from the die.

. 2. vAn apparatus for removing stamped metal articles from male dies,consisting of a perforated cylinder in two parts, hinged together,adapted to encompass the stamped article on the die and to be suspendedfrom its top edge, a gas-supply, a main pipe connected therewith, branchpipes connected with the main pipe, and inlet pipes leading Yfrom thebranch pipes into the cylinder rco through the perforations in thelatter, substantially as described and for the purposes set forth.

In testimony whereof I aftix my signature in presence of two witnesses.
